PHYSICS 102 Lecture Notes - Metalworking, Sintering
Document Summary
Benefits and application of forging: can create parts that are stronger than other metalworking process; forging is. Almost always used where reliability and human safety are critical. ": however, these components are rarely in sight, as they usually feature within assemblies, such as airplanes and so on. Types of forging processes: impression die forging, cold forging, open die forging; and, seamless rolled ring forging. Impression die forging: this process pounds (->30 tonnes) metal between two, or more, dies, known as. Tooling"; these contain a pre-cut profile of the desire part. Cold forging: this process encompasses many diverse variants, namely bending, cold drawing and heating, coining, extrusions, and others. In fact, the temperature of metals being cold forged can range from room temperature to several hundred degrees. Advantages: simple, inexpensive, varied sizes, and yields good strength. Disadvantages: limited to basic geometrics, poor retention of tolerances, machining is necessary, low rate of production, poor utilisation of material, and requires skilled labour.
